Rhizome thick, short-creeping, densely scaly; scales ferruginous, lanceolate, 
serrate; fronds subcespitose, stipe 18-30 cm long, thick, stout, articulated at base, 
dark olive-green, when young, densely clothed in long-stipitate stellate hairs, 
lamina 15-30 cm long, 3-6 cm broad, broadly lanceolate, acuminate, somewhat 
broadened towards unequally subauriculated cordate or rounded base ; texture 
rigidly coriaceous, green, densely pitted and also sparcely stellately hairy above 
when young, densely clothed underneath in thick, reddish-brown persistent in- 
dumentum consisting of appressed stellate uniform hairs with short broad arms 
on the same plan, midrib prominent on both sides, green underneath, dark 
oblive-green above; lateral main veins visible on both sides, oblique, veinlets com- 
pletely hidden, copiously anastomosing with numerous included clavate veinlets; 
sori punctate, dorsal or subapical on included veinlets, distinct at first, finally 
subconfluent. '

One of the most distinct species of the genus, the following species is the 
only close Chinese ally which differs in generally shorter and broader lamina on 
much longer stipe and in very dense loose indumentum on the underside of leaves, 
consisting of long, needle-like arms not on the same plan.
